Is "The Wilbur Cross Parkway (Connecticut Route 15) runs parallel to I-95 west of New Haven, turning northwards as it nears the city and then running northwards parallel to I-91 through the outer rim of New Haven and Hamden, offering an alternative to the I-95/I-91 journey (restricted to non-commercial vehicles)." a good answer to the question "What downtown New Haven expressway spur intersects at exit 1 of 1-91?"
no
